摘要/Abstract

摘要： 在无线传感器网络中,汇聚节点附近的节点在传输数据时需要承受巨大的通信负载,节点能量消耗非常快,容易出现能量空洞问题,因此这片区域变成了整个无线传感器网络的通信瓶颈。为了节省瓶颈区域的能量消耗,通过分析节点的传输范围对节点能耗的影响,合理调整瓶颈区域内节点的传输范围,并结合网络编码方法,提出了TRNC策略。理论分析和数值模拟结果表明,该策略能有效地提高整个网络的能量利用率,并且有助于减少节点的能耗。

Abstract: In a wireless sensor network,the sink’s neighbor nodes have to withstand enormous traffic load in forwarding data,and these nodes run out of their battery power very soon.It is prone to be energy hole problem,thus this zone becomes a communication bottleneck for the whole wireless sensor networks.In order to save energy in the bottleneck zone,the paper proposed the TRNC strategy.It properly adjusts the transmission power range of nodes in the bottleneck zone by analyzing the impact of the transmission power range of the nodes on energy consumption,at the same time,it combines the network coding method.Theoretical analysis and numerical simulation results show that the strategy can effectively improve the energy utilization efficiency and reduce the energy consumption.
